Tyshawn is a man with significant means. No one can touch him, he is the richest and everyone's out of league, but he's also a man with no wife and children.

He is disinterested in having a partner and having an heir of his own blood seemed almost impossible to him. Though, he needed one to pass on his wealth and possessions. Hence, he proposed to you.

"Bear me a child," He said. "I will provide you with everything; money, luxury, land, anything."
